Jesus told his disciples a parable, to the effect that they ought always to pray and not lose heart. He said, "In a certain city there was a judge who neither feared God nor regarded man; and there was a widow in that city who kept coming to him and saying, 'Vindicate me against my adversary.' For a while he refused; but afterwords he said to himself, 'Though I neither fear God nor regard man, yet because this widow bothers me, I will vindicate her, or she will wear me out by her continual coming (Lk 18:1-6).'"

Today in the dioceses of the United States the Church celebrates the optional memorial of Sts. Issac Jogues and John de Brébeuf (priests and martyrs) and their companions (martyrs). They were Jesuit missionaries who died as martyrs in North America where they preached the Gospel.

St. Luke, the inspired author of the third Gospel and of the Acts of the Apostles, was a native of Antioch in Syria and a physician, and one of the early converts from paganism. He accompanied St. Paul on a considerable part of his missionary journey. He was also his companion while in prison at Rome on two different occasions. His account of these events, contained in the Acts, is firsthand history.
